"The new release of the National Information Exchange Model (NIEM), version 2.0, also known as the “Harmony” release, was driven by practitioner requirements through a well-defined collaborative process and brings many great features. Some of the highlights of NIEM 2.0 are:
- Improved semantic quality (harmonization) of the NIEM Core model (Universal and Common) as well as some specific components from the individual domains.
- Remodeling to remove duplication, complexity, and ambiguity.
- Simplification of Universal and Common components to make it easier to understand and use the model, while maintaining their identity of Universal and Common in metadata.
- Domain version independence.
- Integrated ~30 NCCT issues resolved by NBAC/NTAC.
- Addition of five new code lists and types, and updates to existing code lists.
- Migration tools, both for those using NIEM 1.0 as well as those using GJXDM 3.0.3."
